RESUMEN
INTRODUCTION: Strengthening The Reporting Of Cohort Studies in Surgery (STROCSS) guidelines were developed in 2017 in order to improve the reporting quality of observational studies in surgery and updated in 2019. In order to maintain relevance and continue upholding good reporting quality among observational studies in surgery, we aimed to update STROCSS 2019 guidelines. METHODS: A STROCSS 2021 steering group was formed to come up with proposals to update STROCSS 2019 guidelines. An expert panel of researchers assessed these proposals and judged whether they should become part of STROCSS 2021 guidelines or not, through a Delphi consensus exercise. RESULTS: 42 people (89%) completed the DELPHI survey and hence participated in the development of STROCSS 2021 guidelines. All items received a score between 7 and 9 by greater than 70% of the participants, indicating a high level of agreement among the DELPHI group members with the proposed changes to all the items. CONCLUSION: We present updated STROCSS 2021 guidelines to ensure ongoing good reporting quality among observational studies in surgery.

AIMS: To evaluate the results of chemoradiation with intensity-modulated radiation therapy (IMRT) or volumetric-modulated arc therapy (VMAT) for the treatment of anal canal cancer patients at three institutions that had advanced devices. MATERIALS AND METHODS: A retrospective analysis was performed for patients treated with 5-fluorouracil and mitomycin-based chemotherapy and IMRT or VMAT for anal cancer from 2011 to 2013. Complete response (CR) rates, colostomy-free survival (CFS), disease-free survival (DFS), overall survival (OS), and toxicities were investigated. Toxicities were evaluated with the Common Terminology Criteria for Adverse Events, Version 3.0. RESULTS: Fifteen patients were included in the analysis. The majority of patients had T2 (53.3%) and N0 (40%) disease according to the staging system that was developed by the American Joint Committee on Cancer. CR was observed in 14 patients (93%), and the median follow-up was 26 months (13-42 months). The 3-year CFS, DFS, and OS were 86%, 86%, and 88%, respectively. Acute Grade 3 toxicities were observed as 6% of hematological, 26% of gastrointestinal, and 26% of dermatological. CONCLUSION: Early results confirm that IMRT or VMAT for anal cancer treatment reduces acute toxicities while maintaining high control rates.

BACKGROUND: Live donor nephrectomy is an important donor source. Donor nephrectomy can be performed by laparoscopy or hand-assisted laparoscopy. Different types of hand port devices can be used for assistance. In the literature there are few studies about hand-assisted laparoscopy without a hand port. In this study, we aimed to evaluate the impact of not using a hand port for hand-assisted laparoscopic donor nephrectomy for kidney transplantation. METHODS: Patients who were operated on for kidney donation between January 2011 and June 2018 evaluated retrospectively. The patients were divided into 2 groups: group A, on whom a hand port was used, and group B, whose surgeries did not involve a hand port. The groups were compared for sex, age, body mass index, amount of intraoperative bleeding, warm ischemia time, duration of surgery, perioperative complications, duration of hospital stay, and postoperative complications. RESULTS: There were 159 patients in group A and 146 patients in group B. There was no difference between the groups considering intraoperative bleeding, warm ischemia time, duration of surgery and postoperative early complications (P > .05 for all). CONCLUSION: Hand-assisted laparoscopic donor nephrectomy without a hand port can be considered an easy and effective method of laparoscopic nephrectomy.

Idiopathic granulomatous mastitis (IGM) is an inflammatory breast disease with unknown etiology and nonspecific symptoms. Differentiation of breast cancer from granulomatous disease is a diagnostic and clinical challenge. Imaging features and decision of the surgeon, based on these findings, may be important steps during diagnosis and follow-up period. Articles in association with imaging of IGM were evaluated using a PubMed search in August, 2017. Hypo-echoic or heterogeneous mass/es with or without tubular extensions were the most common ultrasonographic findings. Focal asymmetric density with or without skin thickening and parenchymal distortion were detected in most of the patients during mammography. Magnetic resonance imaging most commonly revealed focal or diffuse asymmetrical signal intensity changes without significant mass effect. Although a specified and standardised criteria list for each type of the imaging modality has been lacking, the most commonly detected imaging findings, especially in cases of multiple lesions in accordance with the decision of the surgeon and/or clinician, can be used for the diagnosis and follow-up of IGM with acceptable safety margins. However, in the presence of any suspicious findings during imaging or clinical examination, histopathological analysis should be performed.

INTRODUCTION: Despite recent advances in surgical techniques, pancreatic fistulas are common. We aimed to determine the role of C-reactive protein in the prediction of clinically relevant fistula development. MATERIALS AND METHODS: Data from patients who underwent pancreaticoduodenectomy between 2012 and 2015 is collected. Postoperative 1st, 3rd, and 5th day (POD1, POD3, and POD5) C-reactive protein (CRP) levels, postoperative pancreatic fistula (POPF) development, other complications, length of hospital stay, and mortality were recorded. RESULTS: Of 117 patients, 43 patients (36.8%) developed complications (including fistulas). Of the patients developing fistulas, 21 (17.9%) had POPF A, 2 (1.7%) had POPF B, and 7 (6.0%) had POPF C. POD5 CRP and POD3 CRP were shown to be significantly correlated with mortality and development of clinically relevant POPF (p = 0.001 and p = 0.0001, resp.) and with mortality (p = 0.017), respectively. The development of clinically relevant POPFs (B and C) could be predicted with 90% sensitivity and 82.2% specificity by POD5 CRP cut-off level of 19 mg/dL and with 100% sensitivity and 63.6% specificity by the difference between POD5 and POD1 CRP cut-off level of >2.5 mg/dL. CONCLUSION: CRP levels can effectively predict the development of clinically relevant pancreatic fistulas.
RESUMEN
Breast cancer patients who present with nodal metastasis receive neoadjuvant chemotherapy (NAC) with increasing frequency and can have complete pathologic response after treatment. In this clinical scenario, sentinel node mapping and biopsy are gaining acceptance instead of axillary dissection to avoid morbidity. Biopsy proven positive lymph nodes must be reliably excised and examined after NAC to further decrease the false negativity rate of sentinel lymph node (SLN) surgery. The standard method for axillary staging in breast cancer patients even after NAC is SLN biopsy (SLNB) with a radioisotope, blue dye, or both (dual technique). Currently, preoperative axillary staging with ultrasound and biopsy, along with placement of an image-detectable marker to be removed at the time of definitive surgery is recommended. In this study, we evaluated some methods of SLNB for patients treated with NAC like indocyanine green fluorescence, superparamagnetic iron oxide nanoparticles, indigocarmine blue dye, contrast-enhanced ultrasound using microbubbles, and tattooing. Some methods are also needed to ensure that the initially biopsy proven positive node is removed at the time of surgery to be carefully evaluated for residual disease after chemotherapy like clip placement to the suspected or involved nodes before NAC, and removing the clipped node with the guidance of 125I-labeled radioactive seed or guide wires.

Objective To investigate the role of positron emission tomography (PET) and magnetic resonance imaging (MRI) in evaluating the feasibility of skin-sparing mastectomy in patients with locally-advanced breast cancer (LABC) who will undergo neoadjuvant chemotherapy (NAC) by evaluating the sensitivity and specificity of PET and MRI compared with skin biopsy results before and after NAC treatment. Methods Patients with LABC who were treated with NAC between November 2013 and November 2015 were included in this study. Demographic, clinical, radiological and histopathological features of the patients were recorded. Results A total of 30 patients were included in the study with a mean age of 52.6 years (range, 35-70 years). Sensitivity and specificity for detecting skin involvement in LABC was 100%/10% (62%/85%) with MRI and 60%/80% (12%/92%) with PET before (after) NAC, respectively. When radiological skin involvement was assessed in relation to the final histopathological results, the preNAC PET results and histopathological skin involvement were not significantly different; and there was no difference between postNAC MRI and histopathological skin involvement. Conclusions As preNAC PET and postNAC MRI more accurately determined skin involvement, it might be possible to use these two radiological evaluation methods together to assess patient suitability for skin-sparing mastectomy in selected patients.

Objective Breast cancer awareness month increases public awareness in association with increased rates of screening and new diagnoses. This study aimed to evaluate the effect of breast cancer awareness month on primary diagnosis of breast cancer. Methods Asymptomatic women with the intention of breast cancer screening were included. The non-BCAM (Breast cancer awareness month) group were screened from February to September 2016 and the BCAM group during October 2016. Ultrasound and mammography were performed in all women and in those aged ≥ 40 years, respectively. A BIRADS (Breast Imaging Reporting And Data Systems) score of ≥4 and solid palpable masses without features suggestive of malignancy and/or the physician's preference were regarded as indications for histopathological analysis. Requirement for histopathological analysis and detection of breast cancer were identified as the main variables. Results There were 198 women with a mean age of 49.3 ± 9.5 years. Sixty-nine and 129 women were in the non-BCAM and BCAM groups, respectively. Percutaneous biopsy was performed in seven (10.1%) and three patients (2.3%) in the non-BCAM and BCAM groups, respectively ( P = 0.035). Pathological examinations were benign. Conclusion Although public awareness campaigns lead to increased rates of screening, they may lose their impact on detecting breast cancer because of widespread use of routine screening programs.

Objective To compare urinary iodine excretion levels in patients with breast cancer and control subjects. Methods In this prospective pilot study, patients with breast cancer and normal controls were recruited. Age and menopausal status were recorded. Levels of serum thyroid-stimulating hormone, blood urea nitrogen and creatinine and urine iodine concentration (UIC) were measured. UIC levels were divided into three categories: low (<100 µg/l), normal (100-200 µg/l) or high (>200 µg/l). Results A total of 24 patients with breast cancer and 48 controls were included in the study. There were no statistically significant differences between the two groups with regard to thyroid-stimulating hormone, blood urea nitrogen or creatinine levels. When considered overall, there was no statistical difference in UIC between patients and controls. However, comparisons within each category (low, normal or high UIC) showed a significantly higher percentage of patients with breast cancer had a high UIC compared with controls. Conclusions A high UIC was seen in a significantly higher percentage of patients with breast cancer than controls. UIC may have a role as a marker for breast cancer screening. Further studies evaluating UIC and iodine utilization in patients with breast cancer are warranted.

Carcinoma of the breast, like other malignancies, is a genetic disease with multiple genetic events leading to the malignant phenotype. p53 mutations are the most common genetic events in human cancer. Inactivation of p53 can be a result of mutation in gene sequence. One of the main structures that regulate p53 stabilization is MDM2. It suppresses p53 transcriptional activation by recognizing transactivation domain of p53. The loss of MDM2 function on p53 regulation results in deprivation of p53 tumor suppressor ability. Single nucleotide polymorphisms (SNP309 T->G exchange) or MDM2 amplification has been proposed to play a role in this issue. In the present study, our aim is to analyze p53 and MDM2 status and investigate their interactions in human sporadic breast carcinoma. The study groups were separated according to their molecular classifications. In each group, histologic type of the tumor, conventional prognostic parameters, p53, and MDM2 interactions were compared statistically. Tumors are divided into 4 subtypes due to estrogen and progesterone receptor status, HER-2, and Ki-67 proliferation index results. According to this classification, 23 cases are in the luminal A, 32 cases are in the luminal B, 15 cases are in the HER-2 positive, and 22 cases are in the triple-negative group, with a total of 92 cases. p53 expression is low in luminal breast carcinomas than HER-2 and triple-negative subtypes. MDM2 amplification frequency was found to be 5.4% in total. MDM2 gene amplification does not have a significant role in breast carcinogenesis, but other possible mechanisms may play a role in its inactivation.

BACKGROUND AND OBJECTIVES: Intraoperative use of opioids may be associated with postoperative hyperalgesia and increased analgesic consumption. Side effects due to perioperative use of opioids, such as postoperative nausea and vomiting may delay discharge. We hypothesized that total intravenous anesthesia consisting of lidocaine and dexmedetomidine as an opioid substitute may be an alternative technique for laparoscopic cholecystectomy and would be associated with lower fentanyl requirements in the postoperative period and less incidence of postoperative nausea and vomiting. METHODS: 80 Anesthesiologists I-II adults were scheduled for elective laparoscopic cholecystectomy. Patients were randomly allocated into two groups to have either opioid-free anesthesia with dexmedetomidine, lidocaine, and propofol infusions (Group DL) or opioid-based anesthesia with remifentanil, and propofol infusions (Group RF). All patients received a standard multimodal analgesia regimen. A patient controlled analgesia device was set to deliver IV fentanyl for 6 h after surgery. The primary outcome variable was postoperative fentanyl consumption. RESULTS: Fentanyl consumption at postoperative 2nd hour was statistically significantly less in Group DL, compared with Group RF, which were 75 ± 59 µg and 120 ± 94 µg respectively, while it was comparable at postoperative 6th hour. During anesthesia, there were more hypotensive events in Group RF, while there were more hypertensive events in Group DL, which were both statistically significant. Despite higher recovery times, Group DL had significantly lower pain scores, rescue analgesic and ondansetron need. CONCLUSION: Opioid-free anesthesia with dexmedetomidine, lidocaine and propofol infusions may be an alternative technique for laparoscopic cholecystectomy especially in patients with high risk for postoperative nausea and vomiting. .
JUSTIFICATIVA E OBJETIVOS: O uso de opioides no período intraoperatório pode estar associado à hiperalgesia e ao aumento do consumo de analgésicos no período pós-operatório. Efeitos colaterais como náusea e vômito no período pós-operatório, por causa do uso perioperatório de opioides, podem prolongar a alta. Nossa hipótese foi que a anestesia venosa total com o uso de lidocaína e dexmedetomidina em substituição a opioides pode ser uma técnica opcional para a colecistectomia laparoscópica e estaria associada a uma menor solicitação de fentanil e incidência de náusea e vômito no período pós-operatório. MÉTODOS: Foram programados para colecistectomia laparoscópica eletiva 80 pacientes adultos, estado físico ASA I-II. Os pacientes foram randomicamente alocados em dois grupos para receber anestesia livre de opioides com infusões intravenosas (IV) de dexmedetomidina, lidocaína e propofol (Grupo DL) ou anestesia baseada em opioides com infusões de remifentanil e propofol (Grupo RF). Todos os pacientes receberam um regime padrão de analgesia multimodal. Um dispositivo de analgesia controlada pelo paciente foi ajustado para liberar fentanil IV por seis horas após a cirurgia. O desfecho primário foi o consumo de fentanil no pós-operatório. RESULTADOS: O consumo de fentanil na segunda hora de pós-operatório foi significativamente menor no grupo DL do que no Grupo RF, 75 ± 59 µg e 120 ± 94 µg, respectivamente, mas foi comparável na sexta hora de pós-operatório. Durante a anestesia, houve mais eventos hipotensivos no Grupo RF e mais eventos hipertensivos no grupo DL, ambos estatisticamente significativos. Apesar de apresentar um tempo de recuperação mais prolongado, o Grupo DL apresentou escores de dor e consumo de analgésicos de resgate e de ondansetrona significativamente mais baixos. CONCLUSÃO: A anestesia livre de opioides com infusões de dexmedetomidina, lidocaína e propofol pode ser uma técnica opcional para a colecistectomia laparoscópica, ...

AIM: To describe the radiological findings of idiopathic granulomatous mastitis (IGM). MATERIAL AND METHODS: Radiologic findings of 30 women with histopathological diagnosis of IGM were retrospectively evaluated. All had breast feeding history. All the patients had ultrasonography (US), with 12 of them having additional Doppler US. Of 30 patients, 11 had mammography (MG) and 5 MRI. RESULTS: US showed multiple irregular hypoechoic masses and collection areas with tubular connections in 25 of 30. The collection area with low-level internal echoes but without tubular connections, suggesting an abscess were seen in 2 of 30 (6.6%); a hypoechoic mass with an indistinct border in 2 of 30 (6.6%); multiple milimetric hypoechoic nodular masses in 1 of 30 (3.3%). On MG, normal findings were noted in 5 (45.4%); focal asymmetric density in 4 (36.4%), parenchymal distortion in 1 (9%) and diffuse asymmetric opacity with trabecular thickening in 1 (9%) of 30 patients. On MRI, segmental T2 hyperintensity with contrast-enhancement on T1 were seen in 4 of 5 (80%). An enhancing T2 hypointense mass with irregular margin was present in 1 of 5 (20%). Time-signal intensity curve of lesions showed slow enhancement in 1 and moderate in 4 of 5 patients. CONCLUSIONS: In IGM, MG findings were nonspecific. In US, multiple irregular hypoechoic masses and collections with tubular connections with fingerlike aspects, and fistulae formation to the skin in patients with breastfeeding history suggested IGM rather than carcinoma. Due to the limited number of patients, no conclusion was reached regarding MRI of IGM.

BACKGROUND: Non-invasive evaluation of the extent of axillary nodal involvement in early-stage breast cancer (ESBC) patients and accurate assessment of multifocality are both challenging. Few reports have explored whether 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) might be more useful than other diagnostic methods in these contexts. PURPOSE: To prospectively evaluate the diagnostic utility of FDG PET/CT, contrast-enhanced, and diffusion-weighted magnetic resonance imaging (DCE-MRI and DWI), and sentinel lymph node biopsy (SNB), in detection of axillary metastatic lymph nodes in ESBC patients; and to explore the utilities of FDG PET/CT and DCE-MRI for identification of multifocality. MATERIAL AND METHODS: Twenty-four female patients (mean age, 47 ± 9.9 years; range, 24-68 years) with ESBC underwent whole-body FDG PET/CT and breast MRI prior to operation. SNB and axillary lymph node dissection (ALND) were performed on all patients, as was mastectomy or wide local tumor excision. Histopathological findings served as the gold standard when evaluating either multifocality or axillary nodal involvement. RESULTS: The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy, of PET/CT and DCE-MRI, used to detect multifocality, were as follows: 67% versus 78%, 100% versus 53%, 100% versus 50%, 83% versus 80%, and 88% versus 63%. SNB afforded the highest sensitivity (93%) in terms of detection of axillary metastasis. The sensitivity, NPV, and accuracy of PET/CT were 67%, 62%, and 75% respectively, thus higher than the equivalent values of either DCE-MRI or DWI. CONCLUSION: For assessment of multifocality in ESBC patients, highly specific results of PET/CT should be taken into account along with DCE-MRI findings. For evaluation of axillary nodal involvement, PET/CT has higher sensitivity, NPV, and accuracy values than DCE-MRI and DWI and may guide a surgical decision to proceed or not to SNB or ALND.

BACKGROUND: Multiple breast cancers may present with different clinical and biological characteristics. The data indicate that multifocal (MF), multicentric (MC), and bilateral synchronous (BS) breast cancers (BC) are more aggressive and have an equivalent or moderately poorer survival rate compared with unilateral cases. However, a comparison of these multiple breast cancers has not been covered in the literature. The aim of this study was to describe the histopathological characteristics of patients suffering from MF, MC, and BS breast carcinoma and to compare their prognoses. METHODS: Retrospective data for MF, MC, and BS breast carcinoma patients treated in five different breast cancer units in Turkey between 2003 and 2012 were collected. MF and MC cancers were defined as more than one lesion in the same quadrant or in separate quadrants, respectively. RESULTS: There were 507 patients (271 MF, 147 MC, and 89 BS) treated in this time period. BS breast carcinoma patients were younger than the other groups (44.83 ± 9.6, 47.27 ± 11.6, and 51.11 ± 11.8 years for BS, MF, and MC breast carcinoma patients, respectively). MFBC and MCBC patients in this study were younger than the ages reported in Western literature, but this result was similar to the ages reported in Eastern literature. The five-year survival rates and recurrence rates were not statistically different among groups (P = 0.996 and P = 0.263, respectively). According to univariate analyses, tumor size, histological grade, and lymph node status were statistically significant factors that affected survival. However, only lymph node involvement was significant for survival according to multivariate analyses. CONCLUSIONS: The clinical significance of MF, MC, and BS breast cancers is still unclear and their influence on prognosis is controversial. Disease-free and overall survival rates of BS breast cancers might be similar to MF and MC breast cancers.

BACKGROUND: Means to prevent and control intra- or postoperative bleeding remain a topic of utmost importance in thyroidectomy. In this randomised clinical trial, we used adrenaline spraying to see if it helps bleeding control and reduces drainage and hematoma formation after thyroidectomy. METHODS: After total thyroidectomy, 1 mg/ml adrenaline solution in 10 ml saline was sprayed all over the operation area by a syringe in 40 patients of "Adrenaline (+) Group". In the other 40 patients in "Adrenaline (-) Group", only standart total thyroidectomy was performed. Drainage amounts of 24 hours were recorded. RESULTS: Among 80 patients, 66 (82.5%) were female and 14 (17.5%) were male. The daily drainage amounts of the Adrenaline (+) Group were found statistically significantly lower than the Adrenaline (-) Group (p<0.05). In both of the groups, thyroid volumes were significantly correlated with the drainage amounts. "p" values were 0.008 and <0.001 in Adrenaline (+) and Adrenaline (-) Groups, respectively. CONCLUSIONS: Preliminary experience using adrenaline has been encouraging and it is useful as an adjunct to thyroid surgery in order to prevent hemorrhagia and give up drain placement. But prospective randomized trials using adequate patient numbers are still needed to validate efficacy and safety.
RESUMEN
BACKGROUND: Multifocal breast cancers (MFBCs) present a challenge to surgeons. Although its feasibility is still controversial, breast-conserving surgery (BCS) is not contraindicated for MFBCs. The investigators retrospectively evaluated the feasibility of BCS and reviewed histopathologic findings in patients with MFBC. METHODS: A total of 222 patients with MFBC who were treated with either BCS (119 patients) or mastectomy (103 patients) at a single institution between January 2002 and December 2011 were retrospectively evaluated. RESULTS: The median follow-up time was 55 months (range, 10 to 102 months). Lymphovascular invasion and lymph node involvement were significantly less frequent in the BCS group (48.8% vs 62.2% for lymphovascular invasion, P = .04; 52.1% vs 71.8% for lymph node involvement, P = .002). There were no differences in local recurrence rates between the 2 groups. The overall survival rates were 92% in the BCS group and 72% in the mastectomy group (P = .000). CONCLUSIONS: BCS is a feasible and safe procedure for the removal of multifocal tumors. Extended lymphovascular invasion is associated with mortality in patients who undergo mastectomy.

BACKGROUND/AIM: To describe a novel, easy, and secure thoracoscopic surgical approach for esophageal leiomyomas. MATERIALS AND METHODS: We retrospectively analyzed 18 cases in which patients were treated at a single center between 1991 and 2011 for esophageal leiomyoma. We compared our results of patients who were treated by open surgery with those who were treated by the thoracoscopic approach, and we also compared our results with the results of resection of the leiomyoma of the esophagus in the literature. RESULTS: Eighteen patients were studied. Eight patients were treated with 3-port thoracoscopic surgery, 8 with open thoracotomy, 1 with surgical incision, and 1 with esophagectomy. The mean operating time was 167.5 min and 92.5 min in the thoracotomy and thoracoscopy groups, respectively (P = 0.0012). The average hospital stay was 9 days and 6 days for the thoracotomy and thoracoscopy groups, respectively (P = 0.016). Rupture of esophageal mucosa occurred preoperatively once in both groups and was repaired immediately, and postoperative esophageal leak was not seen in any patient. CONCLUSION: Thoracoscopic enucleation of esophageal leiomyomas is a safe and feasible procedure with decreased hospital stay and operating time. The 3-port technique that we used is a safe and effective procedure, as well.

INTRODUCTION: Mondor's disease (MD) of the breast is a rare condition at breast clinics. We do not have enough data to establish its real prevalence. As a known data, most of the patients that were admitted to breast clinics are not breast cancer. Also MD is a rare entity and diagnosing this entity and informing the patient about it is very important. We present here this case to remind breast clinic practitioners that MD can be seen without trauma (neither surgical nor physical). Also clinical and radiological findings and the treatmentof the MD were discussed. PRESENTATION OF CASE: A 35 year old woman was admitted our clinic with cutaneous breast retraction. She had no risk for thrombosis else using oral contraceptives. Mondor's Disease was diagnosed and supported by radiological findings. Rheumatologic and hematologic causes were also explored. Patient healed in four weeks only with non-steroidal anti-inflammatory drug. DISCUSSION: Mondor's Disease is rarely related with breast cancer. This rare entity can be diagnosed with doubt and patient should be informed about it. Anti-coagulant treatment does not required if disease is idiopathic. CONCLUSION: Mondor's Disease should be reminded at a patient with retracted breast skin.
